I am a relative noob at working with my ESP8266 module to send data to Thinkspeak. I am working on an IoT gardening project based off this project here at:
I have tried many times to compile both components of this project. I am receiving data on serial monitor, and my ESP is connected to my wifi but on thingspeak only receiving a line of zeros.
Here are a few things I have checked: my TX/RX and they are OK, as they get moved in position, my API key is correct, as far as I can tell.
Does anyone have any recommendations they could make? I am stumped.

FYI, MATLAB answers is the preferred location for ThingSpeak Community support.
I recommend you program the esp directly, don't make it a slave to the UNO (as described in the article). If you need more pins, then buy a node MCU esp8266, or a Arduino Nano33 IoT.
Have you tried updating your channel in a browser, just to be sure you have the syntax correct?
I also recommend you use the ThingSpeak library for Arduino
